W W 1. The MPC905 can drive 50 transmission lines on the incident edge. Each output drives one 50 parallel terminated transmission line to
W VTT = VCC/2. Alternately, the device drives up to two 50 series terminated transmission lines per output.
2. XTAL_IN input will sink up to 10mA when driven to 5.5V. There are no reliability concerns associated with the condition. Note that the Enable1
input must be a logic HIGH. Do not take the Enable1 input to a logic LOW with >VCC volts on the XTAL_IN input.
